[0001] The utility model relates to the technical field of maintenance and detection, in particular to a PCB board maintenance and detection device. Background Art

[0002] With the rapid development of electronic technology, PCB, as a key component in electronic equipment, has become increasingly complex and integrated. Various faults are inevitable during the production and use of PCB, such as open circuit, short circuit, component failure, etc. These problems directly affect the performance and reliability of electronic equipment.

[0003] Traditional PCB repair and inspection methods rely heavily on manual visual inspection and simple testing equipment, which can't quickly locate damaged electronic components. Inaccurate holes may appear during the PCB production process, requiring re-inspection of the holes, which is time-consuming and labor-intensive.

[0004] In response to the above problems, this utility model document proposes a PCB board repair and detection device. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art, such as manual visual inspection and simple testing equipment, which cannot quickly find damaged electronic components, and may cause inaccurate holes in PCB boards during the production process, and the holes need to be re-inspected, which is time-consuming and labor-intensive. A PCB board repair and inspection device is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A PCB board repair and inspection device includes a machine platform, a motor fixedly connected to one side of the machine platform, a screw fixedly connected to one end of the motor output shaft, the screw rotatably connected to the interior of the machine platform, a sliding block fixedly connected to the circumferential thread of the screw, an electric push rod fixedly connected to the upper surface of the sliding block, an extension rod fixedly connected to one end of the electric push rod output shaft, and a camera fixedly connected to the bottom of the extension rod;

[0008] Two first guide rails are fixedly connected inside the machine, two second guide rails are slidably connected between the two first guide rails, the first guide rails and the second guide rails are arranged perpendicular to each other, a PCB board is provided above the second guide rail, and the camera is used for maintenance and detection of the PCB board.

[0009] In a possible design, two movable grooves are respectively provided on the upper surfaces of the two second guide rails, and positioning columns are respectively slidably connected in the movable grooves. Positioning holes are provided at the four corners of the PCB board, and the positioning holes cooperate with the positioning columns for detecting and fixing the PCB board.

[0011] In a possible design, a screw is rotatably connected inside the platform, and both of the second guide rails are threadedly connected to the screw.

[0012] In a possible design, a guide column is fixedly connected to the interior of the machine platform, and the sliding block is slidably connected inside the guide column.

[0013] In one possible design, an infrared thermal imager is fixedly connected to the inner wall of one side of the machine platform for quickly locating overheating areas.

[0014] In this application, the PCB board is placed on the supporting surface above the second guide rail, and the positioning columns are moved to the positioning holes at the four corners of the PCB board and fixed with screws and nuts to ensure that the PCB board is stable and immovable. The positions of the two second guide rails can be adjusted by rotating the screws as needed.

[0015] At the same time, the motor drives the screw to rotate, driving the sliding block and the camera to move horizontally to the detection point.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1

[0029] Reference Figures 1-4 A maintenance and inspection device includes a platform 1, which serves as the support platform for the entire device and is designed as a sturdy metal frame to ensure stability and load-bearing capacity. A motor 5 is mounted on one side of the platform 1 and connected to a screw 6 via a transmission device (such as a coupling), providing power to drive the screw 6 to rotate.

[0030] Screw 6 is horizontally mounted and rotatably connected to the interior of the machine 1. Driven by motor 5, it rotates, driving a threaded slider 8 to move axially. Sliding slider 8 is fixed to screw 6 and, through a threaded connection, achieves linear motion as screw 6 rotates. An electric push rod 9 is fixedly connected to its upper surface.

[0031] The electric push rod 9 controls the vertical movement of the extension rod 10 by adjusting the length of its output shaft. The extension rod 10 is fixed to the output shaft of the electric push rod 9. A camera 3 is mounted at the bottom of the extension rod 10 to capture images of the PCB 2 for maintenance and inspection. The camera 3 is a high-resolution camera that captures clear images of the PCB 2 and transmits them in real time to a display screen for analysis.

[0032] Two parallel first guide rails 13 are fixed inside the machine 1 to support and guide the movement of the second guide rail 14. The two second guide rails 14 are slidably connected between the two first guide rails 13, and the spacing between the two second guide rails 14 is adjusted by rotating the screw 15.

[0033] The PCB board 2 to be inspected and repaired is placed on the support surface above the second guide rail 14. Positioning posts 11 are respectively set in the movable grooves on the upper surface of the second guide rail 14, can slide along the movable grooves, and are fixed in the desired position by screws 17 and nuts 18 to position the PCB board 2.

[0034] The second guide rail 14 can be made of plastic material, which has a certain toughness and will not cause damage to the PCB board 2. By tightening the nut 18, the second guide rail 14 can be fastened to the positioning column 11, thereby fixing the position of the positioning column 11.

[0035] The positioning holes 12 designed at the four corners of the PCB board 2 cooperate with the positioning posts 11 to ensure the stability of the PCB board 2 during the inspection process. The positioning holes 12 of the PCB board 2 can also be inspected. If the holes are not opened accurately, it cannot be installed in multiple positioning posts 11.

[0036] Positioning holes 12 are auxiliary holes used in the PCB manufacturing and assembly process. They are usually located at the edge or specific location of the PCB to accurately position and fix the circuit board. These holes do not participate in the connection of the circuit, but are crucial to ensuring the quality and performance of the circuit board.

[0037] This application can be used in the field of PCB boards, and can also be used in other fields applicable to this application.

[0040] A PCB board repair and detection device, which is applied to the PCB board field;

[0041] The guide column 7 is fixed inside the machine platform 1 and is slidably connected to the sliding block 8 to provide vertical guidance for the sliding block 8.

[0042] The infrared thermal imager 4 is mounted on one side of the inner wall of the machine 1 to quickly detect overheated areas on the PCB 2 and assist in maintenance. The infrared thermal imager 4 can be found in the invention patent publication number CN106679824B.

[0043] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 5, the electric push rod 9 and the infrared thermal imager 4 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
